Cellular Respiration

3. Often referred to as glucose, the primary fuel for respiration.
5. The overall goal of breaking down nutrients within a cell.
6. The initial step of respiration that breaks down one glucose molecule into two three-carbon molecules.
7. The three-carbon end product of glycolysis that enters the mitochondria.
8. The gas required for aerobic respiration to act as the final electron acceptor.
9. A gaseous waste product of cellular respiration (exhaled by animals) .
12. The inner compartment of the mitochondrion where the Krebs cycle takes place.
14. A byproduct of fermentation in yeast cells when oxygen is absent.
16. The final stage of aerobic respiration that uses a chain of proteins to produce a large amount of ATP.

1. Produced from carbohydrate breakdown for energy when Oxygen is low.
2. Often called the "powerhouse of the cell," it is the organelle where the majority of ATP is generated.
4. The process by which cells break down glucose to produce energy.
10. The energy-carrying molecule used by cells for power.
11. The jelly-like substance within a cell where the first stage of respiration occurs.
13. A liquid byproduct formed at the end of the electron transport chain.
15. This series of reactions occurs in the mitochondrial matrix.
